This is the method of welding that the US sent technical advisors to the USSR during world war 2 to show the soviets how to make really good welds on the hulls of the soviets tanks. It increased the durability and decreased the production time of the tanks so that the germans had a really bad time on the eastern front. As an example the T-34's made before the war started were good but once production speed was increased, the T-34s were susceptible to having their hulls crack at the joints between the massive plates. So these tanks were literally cracking apart after being driven only 10 or so kilometers. And if they got hit by a high caliber glancing blow the hull would be ruined due to it cracking along all the seams. Afterwards, both speed and quality increased massively allowing the tank factories to outproduce the Germans by a factor of almost 10.
Evidently some people have never seen seem welding equipment for straight line runs. Some people call that track welding equipment. Some of that equipment has multiple adjustment points to follow very irregular seams. I have seen subarc welding equipment with a hand held torch. The massive slag blanket and unmelted flux really help to slow the cooling rate in the weld zone and heat affected zone.
Then you are not keeping up ....well your comments is 7 years old .....wait a minute 6 years ago I was operating a tower trolley sub arc that welded 12-16 foot diameter tower sections together and this would have gotten me FIRED!
I remember reading that the engineers working on Apollo in the 60’s had a problem with their welds and finally decided that the automated welder was the problem. So they took it apart and reengineered it. Great strong welds afterward.
Sometimes, you get a regular guy that absolutely hates the way shit is done and invents a machine to do it so he can get home sooner to drink beer.......and fuck his wife.
i work in pressure vessel fab shop in the east bay California we use this process all the time for our round and straight seams for the large and small pressure vessels and heat exchangers we build. Awsome and super chill process to run if you know what your doing. Set up is the key for a clean sub arc weld.
+Colonel Angus Nice idea for the guy but you really need a lesson in how advertising works, don't set someone up to fall without knowing what goes on first.
One company I worked for bought a new lincoln sub-arc machine and they came in to show us how to use it properly. I am a die hard miller fan but I have to give it to lincoln for doing that.
@@MFKR696 Thank you for that correction, it bothers me that the least informed out there are the most confident when they speak. I used to work at Lincoln Electric in Euclid Ohio and loved seeing these massive pipe welding machines in action!
I am 13 my grandfather was a ironworker for 40 years and he started teaching me to weld when I was 7 and I can now make welds not as clean as that but pretty clean for my 6 years of welding. All my friends think am a nerd because I can use a welder, angle grinder, asleden torch(pretty sure I spelt that wrong) , as well as a plasma cutter. Most of my friends don't even know what those are and it is cool to be able to read the comments on videos like these and be able to understand what people are talking about.
Young man - my salute to you and your grandfather. I'm about to retire from an almost 40 year engineering career - like you - my father taught me to be handy, and he stressed the value of an education as one of the few things in life that once you'd earned it, no one could take it away from you. My childhood dream was to work in the space program - I achieved that (Space Shuttle, JPL, SDI ("Star Wars"), and went on to a second career in medical devices. You are privileged to have at your fingertips the greatest storehouse of information in history - the internet - but you have to process, assimilate, and use it for it to become your knowledge. You're on the right path, and following it diligently is how you will become great. Nurture and grow your curiosity, your thirst, your need for intellectual and physical advancement. Learn to do the things that others can't. Be that nerd - the one that always gets called when one one else has a clue. Improve and polish your communication skills - when you're an accomplished adult, no one will care where you went to school or what your GPA was - they'll judge you by the words you speak and write (acetylene))) and by what you can actually do. Combine this with a kind and gentle character, a healthy sense of humor, and a thick skin, and you'll be as fine a man as you can be. The journey won't be easy, but every life is a struggle - even for those you think "have it all". I wish you the best - I hope that someday when you're about my age, you'll look back and remember this, and think, "that man told me the truth".
Overbuilt automotive and ed federoff thank you so much for those words you sound just like my grandfather. And I will remember these words especially acetylene. :)
That's awesome. I've been encouraging my friends' 15 yr old son and he's taking welding in school and really likes it. Its a better future than becoming a My Little Pony. Just saying. 😏
It can be a bitch/finicky sometimes depending on how it's prepped. Our shit is pretty clean so we don't even etch the oxidation off we just go right to welding. The new machines make it so much nicer and smoother. It's very fast, hot and bright as hell! You'll flash burn yourself in the matter of only a couple min. Literally.
A lot of the 1/4 to 1/2 we weld we run around 24v at around 200 amps. The old standard push pull machines would do the same but at 26v and with lots of spatter. so these new machines will weld the same thickness with better quality using less power :-) 100% duty cycle.
Well it comes at a price. These are about 15k$ machines. Not cheap at all! Funny thing is the power unit is only like 60 pounds and the feeder is like 30 or less lol. Big power in a tinny arse package :-)
I'm sure you seen the newer miller product line. Everything is micro chips and computer boards now. No big several hundo pound machines. Even the plasma cutters rated for 5/8 are suit case size now.
HE IS RUNNING "WAY" OUT SIDE OF PARAMETERS BEING SEMI AUTOMATIC LIKE THAT YOU SHOULD HAVE HAD A MUCH MORE UNIFORM WELD, I COULD DO BETTER FREEHAND WITH DUAL SHIELD OR EVEN CORE SHIELD 6. IF I WERE RUNNING YOUR WELDER, I WOULD HAVE THE INCHES PER MINUTE, VOLTAGE , AND AMPERAGE SO DIALED IN YOU WOULD ONLY SEE A DIME HEIGHTH AND WIDTH WELD WITH PERFECT UNIFORMTY
Haha, this takes me back. Spent 9 months as the offsider on the other side of those 4 ft diameter cans knocking off the slag strips with a hammer (point and chisel-point). Steel was 3/4" thick, and usually took 3-4 rotations to fill the gap (was a wider gap) with cap weld on top to finish. Looks like you don't have a problem with slag strips these days. It was 35 years ago for me. Welders were still Lincoln Electric though, but no fancy digital displays. More or less just a knob for volts and a knob for amps. Nice work :)
you ought to see the long seems process.... five big wires. ran by 7 powerwave welders. we sub arc the ID with four wires and the OD with five wires. we make the PIPE
yes, although what he is welding here is pretty thin. With my machine I start with lower voltage and amperage for the first pass, more of each on the second pass, ditto third pass, and fourth pass and on it remains the same. My setup is also a dual head which I can use on 36" and bigger diameter in which case, the fourth pass I fire up the AC unit.
When I used to repair welders I had to replace a transformer on a 1500amp Lincoln welder used for SAW. After the repair I wanted to make sure everything was working as it should so I went to the factory where it was installed. The operator was joining two 1" I-beams and was running around 1000amps. I had never seen SAW before just MIG and TIG so I was expecting to get a nice sun tan. I put on my welding helmet and stood back a few feet. Needless to say I got a few laughs at my expense.
So... 8 years later, YT recommends a video to me that I A) would never think to look for; B) Something I had NO idea existed; and C) Had too many beers to understand what's going on!! Don't get me wrong, I've dabbled with welding before ...but this...wtf is this sorcery?!?! I think it's pretty cool. I kid around but this stuff IS fascinating to folks like us on the "outside" of these trades!! Pretty cool!
eu fiz um curso de solda de todos os tipos quando era menor de idade no senai do ipiranga isso a mais ou menos 46 anos mas essa solda eu desconheço eu só não segui na profissão porque o gás não me fazia bem era curso gratuito e nós recebíamos leite paulista de garrafa de vidro com a tampinha em alumínio...eu admiro demais o serviço ele é fantástico!!
the flux granules can be reused , but they need to be replenished. they are bits of flux that get melted in the weld puddle in order to form slag that will float out impurities in the steel as well as protect it from oxygen. as for cost effectiveness, the argon is cheaper alone, but the flux is more cost effective as there will be better welds and less porosity. the argon shield is not as effective outside as even a slight breeze will blow away the shielding gas exposing the puddle to oxygen.
Lincoln Power Wave power supplies are possibly as sophisticated as they get. The software is so flexible as far as waveform control and process analysis are concerned that they actually use these power supplies for welding research and development.
This is pretty much the same set up they use at the shop I work at. They are trying to set up a flux recovery so they can use it a few times. Awesome videos!!
This video has just broken 10 MILLION views here on RU-vid today! That's insane and I don't even know what to say about it. I need to thank everyone in the world who is watching my videos! You all rock and I hope you're all doing awesome!
Do this every day on round seams on pressure vessels. Far from perfect, I think its a popular process just because of the sheer amount of metal it can lay down so fast. Alot of ours have to pass x-rays and have a certain amount of imperfection or less. I believe it has a good amount of porosity, but so much is passable. I believe its been around since the 30s, and I wonder how ide never heard of it until i started this job.
It's sending the arc through mixed metal powder that ignites through the arc? That's insane.... I've only ever tried really amateur stick welding to make a stove for a caravan :D that's insane though. Cool job man
Cool. How come the granulated flux doesn't get all in the weld? I thought there would be more smoke and fume than that, as well. Thanks for posting...interesting film.
This is only using one wire for welding. We used twin sub arc process (two welding wires) to repair work rolls at steel mill and I've got a proto type that uses three wires with only one 1500 amp welding power source and have seen 1450 amps while using three 3/32 filler welding wires in same welding head. Lincoln won't talk to me because I'm not an educated engineer even though they don't have this welding system.
In Ireland this is known as Submerged Arc Welding and according to the steel fixer that attempted to teach me how to arc-weld back in the early 1970s the technique was reputed to have been perfected by a team of welders and engineers at the Haarland and Wolfe ship yard in Belfast (wher Titanic was built) and was used initially to butt weld large sheets of plate steel together to form ship-decks etc. Nice demonstration video.
Welding some pipe on cruise control lol nice. I wonder how hard it is to setup though *_* Bead looked really good. I think the fusion on that thing is going to be supreme.
yea, it's a cool vid. I have done some SAW before but never on pipe with a rotator in the field. I was actually curious about how you recover the unused flux. Is it just some type of hopper set up on the back side of the pipe?
13mil viewers ! I used to watch the other guys in the shop welding up big pipes to flanges....it looks kinda boring sitting there all day baby sitting the machine as it goes round n round

been doing this type of welding for 40 years, when you've got your act together, things go smoothly, when things go badly.....time for the gouger and grinder
14 MILLION views as of today! Huge thank you to everyone out there who helped make this possible with your views, likes, and shares! I appreciate all of you!
MrPunisheer Sure me too. Hold my vodka let me try! (I am russian) You fucking piece of shit if you dont fuse when i heat the fuck out of you you wilk get destroyed by russia! *metal fuses itself together*

It's a common practice in heavy industrial welding...it was patented many moons ago in 1935. Used in joining thick plates and piping that can be rotated as is shown here.
I started welding with a Hobart stick welder as a kid back in 68, damn thing was always shocking me but it was fun. Do they still make Hobart machines?
LearningZone the computer was set so all he done was making sure there isnt no flaw or mistake in programming if it was their first machine . in all cool video
